basics.ts

declare const editsc; // Tells TypeScript that this variable is defined elsewhere
editsc.init({
    useVersion: "1.0", // The version of the extension API to use
    name: "Basics",

// Defines an action allowing the user to select a
// block and replace it with a different block
editsc.action({
    context: editsc.context.singleBlock,
    name: "Set block",
    options: [
        editsc.option.block("newBlock"),
    ],
    ui: [
        editsc.ui.input("newBlock", {label: "New block"}), // The new block to replace the old one with
        editsc.ui.button("Set block", function(ctx, opt) {
            ctx.block.replace(opt.newBlock);
        }),
